Built in Dingolfing, Germany, the BMW 6-Series Gran Coupe is a stretched version of the standard 6-Series Coupe, with a wheelbase around 11 cm longer to accommodate rear doors and shoehorn extra room into the back seat.
Coupes traditionally have two doors and rate higher for looks than practicality, but there has been a recent growing trend towards four-door coupes. This head-turning BMW 6-Series Gran Coupe joins an expanding list of similar easier-to-use coupes that include lush rivals such as the Porsche Panamera, Mercedes-Benz CLS and Maserati Quattroporte, and at the more affordable end of the scale, the Volkswagen CC and Citroen DS4.
The appeal of a four-door coupe is clear: eye candy looks but without the awkward clamber into the rear seats that can make a two-door coupe somewhat inconvenient. There is no doubt that this big BMW 640d Gran Coupe has svelte visual elegance. Throughout our time with it, the car pulled attention as unerringly as a strong magnet pulls iron filings.
Built in Dingolfing, Germany, the BMW 6-Series Gran Coupe is a stretched version of the standard 6-Series Coupe, with a wheelbase around 11 cm longer to accommodate rear doors and shoehorn extra room into the back seat. It manages to keep the fine proportions that make the standard two-door Coupe such a looker.
The Gran Coupe engine choice is either petrol or diesel, both three-litre capacity, and the trim and equipment choice is SE or M Sport. Prices of petrol models start from £61,390 for a Gran Coupe 640i SE and rise to £75,315 for a 650i M Sport. Diesels are from £63,900 for a 640d SE and go up to £68,565 for a 640d M Sport.
The 640d Gran Coupe’s engine is a 2,993 cc, six-cylinder unit with 24 valves and twin turbocharging. It is teamed with an eight-speed automatic gearbox with steering column paddle shifts. The engine has stop-start technology to save fuel from being wasted under idling, and to boost the fuel economy, which is not at all bad for a car with this level of performance. The body makes extensive use of aluminium to save weight, which helps optimise performance.
The power output is 308 bhp at 4,400 rpm, and the generous level of torque is 464 lb ft at between 1,500 and 2,500 rpm. The combined fuel figure is over 41 mpg and CO2 emissions are 148 g/km, putting the car in band F for the annual road tax disc. The benefit-in-kind company car taxation rate is 23 per cent.
This car has lots of performance. It is missile-quick, with vivid acceleration, measured in a 0-62 acceleration time below five and a half seconds. The top speed is electronically limited at more than twice the UK limit. It delivers a vibrant driving experience, with the rewarding feel of rear-wheel-drive handling and smoothly rapid cruising manners.
